摘要

Two planar winding structures have been built to compare the characteristics of traditional and alternating winding methods. The alternating winding method reduces the potential difference of adjacent conductors, thus reducing substantially the self-capacitance in the winding. Measurements confirmed that the two inductors have similar equivalent inductance and low-frequency series resistance. However, the alternating winding method has a higher self resonant frequency. It is also evident that the reduction of self-capacitance in the winding not only increased the operating bandwidth of the device but also reduced the power losses of the inductor at high frequency.
